Damayogenius18:Note rate of diffusion is inversely proportional to d relative atomic mass naw did says Dat d lower d diffusion rate d higher d molar mass of such element For a gas to have a low diffusion rate d gas must have strong intermolecular force to bind dem together and resit set independent motion of d molecules of d gases in question Whit did said Oxygen has d highest molecular mass hear so it has d lowest diffusion rate giving it d highest molecular force In contract hydrogen has low molecular mass hence it posses d lowest intermolecular force... Answer is A Also note dat d lower d density d lower d intermolecular force Dis explains y hydrogen is used to fill balloon Helium. Is also used but Dat if hydrogen moves faster due to loosened inter force..... I rest my case |

Damayogenius18: Answer.. Covalet bond Y?? Ok c D carbon as 4 electrons abi..valency oo Oxygen as 6 abi ..... Now for dem to complete an octet rule each must have 8 valences abi If carbon donates 2 electrons And oxygen 4 Electons it mins 6 Electons Is binding dem together abi forming a triple covalet bond between dem Now draw what I just said in a paper and count d number of electrons in each participating atom. (oxygen and carbon) What did u find out each as a complete octet abi Day solves it But our oga go say wrong But Dat d answer oo |

Good morning Which of the following oxides will NOT dissolve in both dilute hydrochloric acid and 2M sodium hydroxide solution? a) Lead (II) oxide b) Aluminium oxide c) Zinc(II) oxide d) Calcium oxide |

Papi112:..Doc,what you fail to understand is that,there are alw exception...I believe that's y many ppl keep smiling after post utme thinking they have answered many question correctly BT when the result comes out,they get less than they expected...in your preparation, its good to knw abt trend( like Electron affinity decrease down the group).. The exception is btw chlorine and fluorine....chlorine has higher electron affinity that fluorine...I recently discover this,that y I asked so that all of you can know...I bliv that's how UI trap ppl( esp the brilliant minds) 1 Like |

dolapo74:..lead will form ppt with dilute HCl but Al and Zn will dissolve.. The answer can't be B or C..calcium oxide is ionic,it will dissolve in HCl( by reactio ) to form calcium chloride and water..answer should be A.. |

Whenever you read abt anything..make sure you know the trend and also the exceptions..In Carbon monoxide...carbon form two covalent bond and one dative bond with oxygen ...oxygen is the electron pair donor.....Electro Affinity is the energy released when a gaseous atom accept electron to form a gaseous negative ion..it decrease down the group because as we go down the group,a shell is added and the attraction of the positive nucleus to the electron decreases..so,the more the shell,the lesser the "EA"..the trend is ok from chlorine to iodine BT the exception is BTW chlorine and fluorine..... Although fluorine has lessee shell than chlorine e,it is too small..adding electron to it will cause little repulsion which lessened is EA than chlorine... 3 Likes |

In case of Intermolecular force,hydrogen shld normally av the lowest BT when I was reading, i saw this and I think it is appropriate to share it with you guys...the weakest intermolecular force is vander Waal's force...vander waal force increases as the number of electron of a species increases...hydrogen has the least electron and should have the least Intermolecular force BT somehow its helium.... I dnt also know why... A way around this is to remember that.. Helium is the most ideal gas(followed by hydrogen) the reason is because it has the least Intermolecular force....thanks guys... Am signing out finally.. |

You all should forget about ur jamb scores o... U all got zero... *lol* no seriously.... the same person that got 200 n another day got 350 will still write the putme....And your jamb scores wnt be added into ur putme score o... So if u got 200 or 350, una get the same chance of getting admitted.. |
